Application filed December To all whom z'tm ay' concern Be it known thatI, Fonnns'r G.'V'PURI NT ON;,-* a citizen of the United States .of Amer ca,

' residing at W aterbu'ry,'in the county of New securely anchor the button to the cloth. 1

Heretofore, as far as I am aware, it has been theppractice to drive a tack into a thin perforate or imperforate shell which has to be placed or formedoin the button head, and in many instances, it was necessary to place a hard metal plate within the button head in the form of an anvil or baflie .plate to turn the point of the tack or staple either in the desired direction or to prevent it from passing through the head of the button.

One of the objects, therefore, of present invention is to construct a button head of relatively soft material and to provide a fastener which I have shown as. a double prong tack or staple, which is to;be vforced bodily into the rear ofjthe head'of the but ton and due to the softness of the material of the button head, the hardness of the staple, and the beveling of the prongs of.

Referring now to the accompanying draw Fig. 13 is a sectional view showing an ornamental form of button with the prongs in position,

Fig. 14 is a View of the staple driven into the head, the prongs being shown curled outwardly,

Fig. 15 is a sectional view of a button head, the ends of the prongs beveled but slightly, and

Fig. 16 shows the staple driven within the button head and the prongs curving parallel with relation to each other.

Referring now more particularly to the several views, there is shown in Fig. 1 a blank 1 of relatively soft material, such as pure aluminum, which blank is cut from a long rod or wire of this metal, after which the blank is subjected to proper dies, not shown, to form the button head 2, which is preferably provided with the hub 3 while the face of the button may have stamped therein any desired ornamental configuration as at 4;, and, in the present instance, the configuration shown in Figs. 1 to 10 is one that forms the subject matter of a design patent filed by Leonard R. Carley, October 22, 1924, bearing Serial Number 11,141. It will. be understood, however, that the shape of the button head, as well as the configuration on the face thereof, may be of any desired shape, or form, the ones shown being simply for the purpose of illustration.

may be slightly beveled as at 10, so that Referring now to Figs. 3 and 4:, there is shown formed in the hub 3 a slight annular depression 5 which in turn forms the f-rusto conical projection 6 centrally of the hub, and it is here also to be understood that the sloping side walls of the depression 5 might be more pronounced, or nearer the vertical.

After reference has been made to the staples and the manner in which they are forced into the hub, further reference will be made to the annular depression 5 as the shape of this depression, together with the beveling of the staples is what makes it possible to predetermine the way in which the prongs should be curled. V

Referring now to the several views showing the metallic fastener, it will be seen that it may be a staple having two prongs 7 having the integral portion 8, similar to the staple, as shown in the patent to F. R. White, No. 1,110,091, patented September 8, 1914, over which is placed the ornamental cover 9, or it may be formed in any desired way, providing, however, it is a double prong fastener of relatively hard material.

These prongs 7, as will be noticed in Fig. 9,

when these rongs are forced into the metal as will be shortly described, they will tend to curl inwardly as shown at 11 in Fig. 10.

To fasten the button head 2 to the cloth, the button will bepl-acedin a button attaching machine (not shown) the button heads in one magazine and the staples in the other, and after the staple and head have been automatically fed in position, the plunger (not shown) will force the staple into the button head, the walls of the central projection 6 in the hub initially centering the prongs. As the staple is forced to its final position, the prongs will be stunted and curl within the head as clearly shown in Fig. 10, thereby tightly anchoring the head to the fabric and to the staple.

Referring more specifically to the depression or groove 5 it is primarily designed to locate the staple concentrically to the hub' of the button in the attaching operation.

In the attaching, if the prongs of the staple approach the hub of the button a little to one side or the other, the beveled sides of the annular groove cause the points of the staple to skid back into alignment with the hub so that the points actually break through the surfaces of the hub in the bottom of the depression and on opposite sides of the center.

There is still another function of this annular groove nearly as important as that stated above, I have found that the most dependable results in attaching can be only obtained by first giving this annular depression in the base of the hub a particular shape, that is, V-shape in cross section which may vary slightly toward U-shape in cross section; second by making the diameter measure from the bottom of the V on one side, to the bottom of the V on the other side, a little less than the distance between the points of the staple; and third, making the angle of the V correspond with the angle of the bevel on the points of the staples.

This may be more readily understood by referring to Figs. 11 to 16 inclusive, and now, taking up first Figs. 11 and 12, there is shown a common form of button head 15 having the hub 16 which is provided with the annular depression 17 leaving the sin-all central projection 18, and in this instance the depression is substantially V shape, and

it will be noticed that the slopingwall 19 corresponds in angularity to the several beveled poi11ts'20 of the prongs 21.

When this staple is forced into the material 22 and into the hub 16', the prongs will. curl towards each other as shown at 23, the curling action in this instance, therefore, being similar to Fig. 10, but it will be noticed that the depression in the hub is slightly different in shape than that shown in Fig.

10, the central projection 18 being smaller in diameter than the projection 6, as shown in Figs. 8, rand 10. It is also to be remembered that in one instance the button is of the common form and in the other it is the ornamental form.

Referring now to the form shown in Figs.

13 and 14, a thick headed button 24 is shown with an annular depression 25 the walls be ing beveled as at 26, leaving;- the -more" rounded projection 27 and in this instance the prongs of the staple 28 are beveled on their inside, the sloping inner walls of ,.the depression corresponding withv the bevel, thus causing the prongs to curl outwardly as at 29, as shown in Fig. 14.

they are initially made. I

InjFig. 6 I have shown a biitton i-head 12, a' hub e131and a plane surface 14%, in which itflis possible to force a metal staple but it is to be understood that by far thepreferred form is to forma substantiallyV-shaped depress ion in "the 'hub so that the prongs .of

the staple will be centered and also guided in their initial piercing of the metaly Thus, it will be seen that when it is desired to fasten an ordinary form of lbutton with a staple, rongs beveled in a certain way and the hu provided with a ,V-shaped groove, will cause the arms to lock within the metal in a restricted area. Again,

where a special form of thick headed but-f ton is used, the prongsmay be made to curl outwardly, this providing the strongest form of connection, and once more, inasmuch as the staples may be initially made with a slight bevel on theirjlikeside, they 7 head and will may be driven into a button bend in parallel relation.

From the foregoing it willlOe seen that I have produced buttons that are neat'in apprearance, may be made at a maximum speed om soft metal blanks, and maybe readily attached by theuse of hardfmetal staples, and after ones being fastened, cannot be pulled apart- At the same time, it "is not necessary to provide the button headslwith internal hubs of hard material,-perforate or imperforate; plates, nor anvils or baffle plates. l

The button head might be made of other soft composite metals or alloys, rather "than aluminum, but I have found thatabutton' head of pure aluminum will not tarnish, takes a clean cut impression from the dies,

and is soft enoughto permit the prongs of the staple to plunge thereinto, but at the Q: e V
